The techniques and methods supplement traditional methods of material identification like hard stamping. They are intended to increase confidence level in materials actually meeting specification.

This British Standard provides guidance on the supplementary checking of metallic materials used in operational plant and in the manufacture of pressurized systems including components such as piping, pressure vessels, valves, pumps, fired heaters, boilers and associated weld deposits, etc. It is valid for checking either on site or at earlier stages, e.g. at the pressure component manufacturers, stockists or fabricators. These additional checks are intended to increase the level of confidence established by traditional methods of material identification and recording.

This British Standard is not intended to be applied in the material manufacturer’s works.
